风机翼型气动特性数值模拟研究

摘要

In this paper, a wind turbine airfoil S809 is simulated based on CFD. Its pressure coefficient with different angles of attack was obtained. The numerical results are compared with the experimental data, which proves the feasibility about our approach to predict aerodynamics performance. The theoretical foundation is established for three-dimensional flow simulation of airfoil in the future.%　　本文基于计算流体力学对风机S809翼型进行了数值模拟，计算了不同攻角下的压力系数分布，结果表明不同攻角下模拟结果与实验数据吻合较好，证明所提模拟方法预测气动性能的可行性，为进一步对翼型进行三维流动模拟奠定了理论基础。
